Shared space er et relativt ukjent konsept i Norge, og det er derfor vanskelig å konkludere med hva som er riktig fremgangsmåte i disse plansakene. I tilfellet med Universitetsgata har man opplevd at mangelen på kunnskap om hvordan shared space fungerer i Norge har gjort prosessen vanskelig. Det er gått med mye tid på å diskutere hva shared space er, i stedet for å diskutere utformingen av Universitetsgata. Brukermedvirkning er en viktig del av norsk plantradisjon, men det er viktig at kun relevante problemstillinger blir diskutert. The concept of shared space integrates all road user groups in the same urban space. The idea of the concept is that by removing regulations and street markings, the road users will have to relate to each other on a greater scale in order to navigate. This may have a positive effect on both safety and accessibility. Through statutory citizen participation, residents and other interested parties have the opportunity to provide input to the planning and thereby help to determine the design of a site. The degree of participation varies on the different projects. In some cases there is no more involvement than the minimum requirement of the Planning and Building Act, while other projects have a high degree of participation through for instance information meetings and planning workshops. Extensive participation processes do not necessarily lead to better design, but may reveal challenges that otherwise may have remained unknown. Today, there is no overall definition of how shared space should be designed, and this can create challenges in the planning of new projects. The thesis examines the theory behind shared space and citizen participation, and discusses at processes behind the design of St. Olav's plass and Universitetsgata in Oslo. Through this I try to uncover who is setting the terms for the design of shared space. This is also my approach to the problem. Shared space is a relatively unknown concept in Norway, and it is therefore difficult to make conclusions regarding what is the correct procedure in these planning issues. In the case of Universitetsgata, the citizen participation has uncovered the lack of knowledge about how shared space functions in Norway. This has made the process difficult. Rather than to discuss the design of Universitetsgata, Time has been spent discussing the definition of shared space. User participation is an important part of the Norwegian planning tradition, but it is important that only relevant issues are discussed.
